BURNER.

Application filed may 27,

To aZZw/zom it may concern:

Be it known that we, Emrnn E. Connwnnn and JosnrI-r H. MoCnnAnY, citizens of the United States, andresidents of Olnnulgee, in the county of Okmulgee and State of Oklahoma, have invented certain new and useful Improvements in Burners, of which the following is a specification.

This invention relates to an improvement in gas burners of the type forming the subject-matter of our Patents Nos. 1,405,100 and 1,405,101. Q

The object of our invention is to provide a burner of this character wherein. the proportion of air-and gas may be conven iently regulated so as to insure-a generation of a highly combustible mixture and under varying conditions thereby insuring at all times a generation of a high degree of'heat and in general an eflicient operation on part of the burner. v

A further object is to provide a burner structure wherein the mixing chamber and the gas chamber are highly organized and are positively supported in adjusted relation with respect to each other.

Another object is to provide a device of this character which is of simple and durable construction, reliable and efficient in operation and easy and comparatively inexpensive to manufacture. 7

Other objects and advantagesof the in vention reside in certain novel features of the construction, combination and arrangement of parts which will be hereinafter more fully described and particularly pointed out in the appended claims, reference being had to the accompanying drawings forming part of this specification, and in which:

Figure 1 is a view in side elevation, showing the preferred embodiment of the in vention;

Figure 2 is a view in longitudinal vertical section;

Figure 3 is a view in rear elevation;

Figure 4 is a detail view in elevation of the rotatable damper; and

Figure 5 is a view in elevation of the rear end of the mixing chamber, the fuel chamher and the rotatable damper being removed.

Referring to the drawings, the numeral 10 designates an open ended shell having a section 11 of elliptical cross section and converging toward the free end thereof,

and a section 12 integral with the section 11, the section 12 being circular in cross section and of frusto-conical form. The section 11 constitutes a nozzle and the section; 12 constitutes amixing chamber, as will hereinafter more fully appear.

As shown in Figures 2 and '5, the larg end of-the section 12 has integrally formed therewith a series of inwardly and radially extending and spaced wings 13, the spaces between the wings being indicated at 14 and constituting air inlet openings. The inner edges of the wings 13 are beveled. as at 13 to constitute seats, as will be understood.

A. fuel chamber designated generally at 15 is arranged in cooperativerelation with respect to the mixing chamber constituted by the section 12 of the shell. the gas chamber comprises an inner cylindrical wall 16, an outer wall made up of acylindrical section 17 and an integral frusto-conical section 18 and end walls 19 and 20, both of which are integrally formed with the. inner wall 16, the end wall 19. be ingalso integrally formed with the cylindrical. section 17 of the outer wall and the end wall20 being also cylindrically formed With th;flllStO-C0llll3tl section 18 of the outer wall whereby the walls define an enclosed fuelspace 21. to which gas is'sup plied to any suitable source through a connection22. The end wall 20 of the gas chamber is disposed atthe outlet end of the chamber and it is provided with a multiplicity of discharge openings or orifices 23 arranged in circular series. At the discharge or outlet end of the gas chamber the section 18 of the outer wall is provided with a shouldered seat 24 which engages the seats 13 of the wings 13 in assembly and the gas chamber is supported in this manner and in proper relation with re spect to the mixing chamber by means of straps orarms 25 secured, as at 26, to the shell 10 and adjustably secured to the gas chamber by means of nuts and bolts 27 carried by the fuel chamber and cooperable with elongated slots 28 provided in the straps or arms 25.

A rotatable damper, designated generally at 30 abuts the large end of the mixing chamber 12 and encircles the adjacent portion of the gas chamber 15. This damper comprises a ring 31 having integrally Preferably provided in the section 18 of the gas cham-' her and an annular rib overlaps the large end of the shell 10 whereby the damper :is constrained to rotary movement. A handle or lug 36ifacilitates manipulation or the damper. It isobviousrthat the damper-may be adjusted so that its wings 32 are stag-- gered with. respect to the wings 13 and consequently lie acrossthe airvinlet openings 14 preventing inflow of air :through these'openingsor on the otherhand the damper may beso-adjustedas to dispose the wings 32 in alinement with the swings 13 leaving the spaces 14: open and permitting flow of air through these spaces. A swinging damper 38:0011t10ll8dib3 aset screw 33.7 regulates the flowof air thiz'ou-gh' the axial opening of the gas chamber. f

In operation, gas being supplied to the space 21 it is discharged in the form of a multiplicity of ets from the discharge openings23 and into the mixing chamber 19, wherein it commingles with the air flowing through the axial opening of the gas chamher and flowing through the inlet opening l l'i'f'the chamber '30"be opened. The cham-' ber 80 maybe adjusted "to give the mixture the desired proportion of an so as to adapt the burner to varying conditions. The mixt-ure'is in thevmain formed in the chamber 12 but the comming'ling action progresses in the chamber defined bythe section 11 which also constitutes the nozzleo'f the burner. In this manner a highly combustible mixture may be obt'ainedunder various conditions.

section, the large section merging at its small end into the small section and the small section tapering toward its outlet end, and a gas chamber arranged at the open end of the large section and madeup of an inner cylindrical wall defining anax'ial air passage,

an outer wall including a cylindrical section and a frusto conical section, the irustoconical section converging toward the large end of the shell and coacting with this largeend to define an air inlet into said shell, said gas chamber also having end .walls integral with the inner and outer walls to define therewith an enclosed gas space, the end wall adjacent the shell having a circular series of discharge openings.

In a burner, a mixing chamber having a series of spaced and inwardly extending wings at its inlet end, the wings defining air inlet openings, a gas chamber engaged with the inner ends of the Wings of the mix ing chamber and a rotatable damper abut-' ting the inlet endiof the mixing chamber and encircling the gas chamber andcomprising a ring having a series of wings spaced from each other and extending inwardly and coop'erable with the wings of the mixing chamber to regulate the flow of air through the airinletopenings, said gas chamber having a channel in which the "inner-ends of the wings of the damper are received, the damper having an annular rib overlapping the adjacent end of the mixing cham er'.
